7 Natural Sources for Stronger, Healthier Lungs

1. Peppermint

THE SCOOP:

Minty fresh breath is beneficial not only to those around you, but to your body, too. The American Cancer Society points to peppermint oil for treating ailments of the lungs, while recent research shows that the herb may help athletes breathe better. In an Iranian study published in the Journal of the International Society of Sports Nutrition, participants who drank water spiked with peppermint essential oil had improved respiratory rates, probably because of the way the mint relaxed their bronchial muscles.

FOR BETTER AIR:

Add 3 to 4 drops to hot water for inhalation, which is the dosage recommended by the American Cancer Society. The amount used in the study, meanwhile, was 0.05 milliliters of peppermint oil in 500 milliliters of mineral water.

2. Eucalyptus

THE SCOOP:

If just the thought of vacationing in Australia causes you to sigh deeply, there may a reason. Eucalyptus, which grows naturally in the Land Down Under, has been shown to prevent bronchitis flare-ups when combined with two other essential oils containing components of lime and pine. That also explains why cough drops often contain extracts of the eucalyptus plant.

FOR BETTER AIR:

Add a few drops of eucalyptus oil to a bowl of boiling water (place a towel over your head to make a tent to contain steam) then close your eyes and slowly breathe in the vapors for 10 minutes. A study in the Alternative Medicine Review notes this method is effective for easing symptoms of respiratory infections, rhinitis and sinusitis thanks to the oil’s antibacterial, antiviral and anti-inflammatory properties.

3. Vitamin D

THE SCOOP:

People who are deficient in vitamin D may be more likely to get respiratory tract infections, according to a recent report in Vitamins & Hormones. The study authors also point to the sunshine vitamin as a possible treatment for asthma.

FOR BETTER AIR:

While the Institute of Medicine’s Food and Nutrition Board recommends getting 600 IU of vitamin D daily, the tolerable upper intake level is 4,000 IU daily. Ask your health-care provider if a supplement is right for you.

4. Tea

THE SCOOP:

In a Journal of Inflammation study using guinea pigs, the harmful effects of cigarette smoke – oxidative stress, inflammation, programmed cell death (apoptosis) and lung injury – were prevented by an infusion of black tea. Like many other food sources that can help improve lung health, it seems to be the tea’s high antioxidant content that provides the benefits.

BETTER-AIR FARE:

Choose black tea over black coffee as a morning warm-up or an afternoon pick-me-up.

5. Whey protein

THE SCOOP:

Can whey guide the way to a clearer respiratory system? At least one study has reported that supplementing with whey based products can help patients with cystic fibrosis. That’s because whey increases levels of glutathione, an antioxidant that defends against damage to the lungs.

6. Apples

THE SCOOP:

An apple a day may keep lung problems at bay, a recent report out of London reveals. Researchers from St. George’s Hospital Medical School discovered that among 2,500 study participants, those who had five or more apples per week had slightly better overall lung function. Quercetin, an antioxidant found in apples, may help protect the lungs against smoke and other pollutants.

BETTER-AIR FARE:

Pick organic apples over other fruits as a late-afternoon snack (apples have also been shown to improve alertness).

Blueberries

THE SCOOP:

Lately, the news on blues has been good, with studies linking the berries to improved heart health, sharper brains and even slimmer waistlines. Now, researchers reveal that blueberries – which pack more antioxidant punch than most other produce – may reduce the harmful effects of air pollution. In an observational study presented at the American Heart Association’s annual meeting in 2014, scientists found that changes in heart function during heavy smog days around Boston tended to be less likely among elderly male participants who had recently eaten flavonoid-rich foods such as blueberries. (Chocolate and wine are also full of flavonoids, but contain more calories, which could counteract the benefits.) It’s suspected that flavonoids may help regulate the immune system and even “reprogram genes” to protect you against air pollution.

BETTER-AIR FARE:

Add 3/4 cup blueberries (the amount consumed each day in the study) to Greek yogurt, smoothies and salads, or just pop them plain.

Does seasonal affective disorder (SAD) really exist? The question over blues resulting from reduced levels of sunlight has become a hot one since a 2015 study in Clinical Psychological Science reported that “the idea of seasonal depression may be strongly rooted in folk psychology, but it is not supported by objective data.” Still, with an estimated 10 million Americans suffering from SAD, and with many feeling stressed by the demands of winter, it’s worth a look at the nutrients and therapies that may help keep your happy face on through spring.
